MicroPython libraries

Functionality specific to the MicroPython implementation is available in the following library.

• micropython – access and control MicroPython internals

Python standard libraries

The following standard Python libraries are built in to MicroPython.

For additional libraries, please download them from the micropython-lib repository.

• cmath – mathematical functions for complex numbers
• gc – control the garbage collector
• math – mathematical functions
• os – basic “operating system” services
• select – wait for events on a set of streams
• struct – pack and unpack primitive data types
• sys – system specific functions
• time – time related functions

Python micro-libraries

The following standard Python libraries have been “micro-ified” to fit in with the philosophy of MicroPython. They provide the core functionality of that module and are intended to be a drop-in replacement for the standard Python library.

The modules are available by their u-name, and also by their non-u-name. The non-u-name can be overridden by a file of that name in your package path. For example, import json will first search for a file json.py or directory json and load that package if it is found. If nothing is found, it will fallback to loading the built-in ujson module.

• ubinascii – binary/ASCII conversions
• uctypes – access C structures
• uhashlib – hashing algorithm
• uheapq – heap queue algorithm
• ujson – JSON encoding and decoding
• ure – regular expressions
• usocket – socket module
• uzlib – zlib decompression
